Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678380, here are decompositions:

17 + 8678363 = 8678380
41 + 8678339 = 8678380
47 + 8678333 = 8678380
167 + 8678213 = 8678380
233 + 8678147 = 8678380
239 + 8678141 = 8678380
251 + 8678129 = 8678380
311 + 8678069 = 8678380

Showing the first eight; more decompositions exist.
